Remote deployment of monitoring agents on computing systems

ABSTRACT

User input is obtained at a central monitoring device to deploy a monitoring agent at a host computing node. Based on the user input, a job is identified to be executed by a deployment server to deploy the monitoring agent at the host computing node. An execution time window is identified to execute the job at the host computing node. The deployment server is accessed using a service account that does not require human intervention and the execution of the job is triggered within the execution time window to cause the deployment server to deploy the monitoring agent at the host computing node.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/943,360 filed Jul. 30, 2020, by Annamalai Arunachalam, and entitled “REMOTE DEPLOYMENT OF MONITORING AGENTS ON COMPUTING SYSTEMS,” which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates generally to monitoring computing systems, and more specifically to remote deployment of monitoring agents on computing systems.

BACKGROUND

In large enterprises, monitoring performance of computing systems and applications is a formidable task. For example, a large enterprise typically maintains a distributed enterprise network including multiple clusters of computing nodes spread over a large geographical region which makes the network difficult to monitor. Existing monitoring solutions do not provide an efficient method to deploy monitoring agents across host computing nodes of the enterprise network and collect log data from the host computing nodes. Traditional methods for deploying monitoring agents at host computing nodes are complicated and prone to errors.

SUMMARY

The system and methods implemented by the system as disclosed in the present disclosure provide technical solutions to the technical problems faced by current technology by, among other things, efficiently and consistently deploying monitoring agents across host computing nodes with a high degree of accuracy. The disclosed system and methods provide several practical applications and technical advantages.

A central monitoring device (e.g., a central monitoring server) is provided that is operatively coupled to a deployment server, wherein the deployment server is configured to deploy a set of monitoring agents at the plurality of host computing nodes. A user may use a front-end client device connected with the central monitoring device to specify input parameters for deploying a monitoring agent at a host computing node. The input parameters may include an identity of a user requesting the deployment, an identity of the host computing node, an indication of the monitoring agent and an indication that the monitoring agent is to be deployed at the host computing node. A monitoring manager at the central client device is configured to carry out the requested deployment based on the user input obtained from the user. For example, based on the user input obtained from front end client device, the monitoring agent selects an appropriate deployment job that can be executed to carry out the requested deployment. The monitoring manager further identifies an execution time window within which the deployment job can be executed at the host computing node. The monitoring manager then accesses the deployment server using a service account that does not require human intervention and triggers execution of the deployment job at the deployment server within the execution time window to cause the deployment server to deploy the monitoring agent at the host computing node.

The above method for deployment of a monitoring agent at a host computing node allows deployment of monitoring agents across host computing nodes with a high degree of consistency, accuracy and speed. The disclosed system and methods accept a limited set of input parameters from the user and automatically determine a remaining set of input parameters needed to deploy a monitoring agent at a host computing node. For example, the user only needs to provide an identity of the monitoring agent and the identity of the host computing node at which the specified monitoring agent is to be deployed. Based on these very limited user input, the monitoring manager determines a custom deployment job to be used for the deployment, a job path where the deployment job can be accessed, an execution time window related to the specified host computing node, an estimated time for completion of the deployment, a service account to use for the deployment etc. By automatically determining several input parameters to use for the deployment, the disclosed system and methods allow for deployment of monitoring agents with relative ease and at the same time maintain high degrees of accuracy. The disclosed methods significantly reduce user effort and allow for an easy and uncomplicated user interface at the front-end client device. Further, the system and methods include a mechanism for detecting unsuccessful deployment attempts and automatically re-triggering the deployment, thus ensuring that a monitoring agent is properly deployed at a host computing node.

DETAILED DESCRIPTION

System Overview

FIG. 1 is a schematic diagram of a monitoring system 100 for monitoring performance and availability of systems and applications in an enterprise network, in accordance with certain embodiments of the present disclosure.

Monitoring Infrastructures

As shown, the monitoring system 100 includes a plurality of monitoring infrastructures 110. A large enterprise typically maintains a distributed enterprise network including multiple clusters of computing nodes. For example, the enterprise network may be divided by regions (e.g., continent, country, province, state, city, etc.), wherein each region is associated with a regional cluster of computing nodes of the enterprise network. A monitoring system (e.g., monitoring system 100) designed to monitor performance and availability of systems and applications within the enterprise network may be divided into several monitoring infrastructures, wherein each monitoring infrastructure is responsible to monitor parameters related to a particular cluster of computing nodes of the enterprise network. FIG. 1 shows two such monitoring infrastructures 110 a and 110 b as part of the monitoring system 100. In an embodiment, each of the monitoring infrastructures 110 a and 110 b is configured to monitor parameters for a different regional cluster of computing nodes of an enterprise network. For example, as shown in FIG. 1 , monitoring infrastructure 110 a is configured to monitor parameters related to computing nodes 118 a-c. Similarly, monitoring infrastructure 110 b is configured to monitor parameters related to computing nodes 118 d-f. The parameters that may be monitored by the monitoring system 100 may include CPU (central processing unit) metrics, disk space metrics, invalid login attempts and other parameters that indicate availability and/or performance of a system or application within an enterprise network.

While FIG. 1 shows two monitoring infrastructures, a skilled person may appreciate that the monitoring system 100 may include less than two or more than two monitoring infrastructures depending on a size and architecture of the enterprise network the monitoring system 100 is designed to monitor.

Each of the monitoring infrastructures 110 is based on a server-client-agent architecture following a hub-spoke model. Monitoring agents 120 are installed at computing nodes 118 of an enterprise network. A computing node 118 may also be referred to as a host computing node or simply a host node as it hosts the monitoring agent 120 that is configured to monitor the computing node 118. The terms computing node, host computing node and host node are used interchangeably throughout this disclosure. As shown in FIG. 1 , monitoring agents 120 a-f monitor computing nodes 118 a-f respectively. In an embodiment, one or more monitoring agents 120 may be configured to monitor each computing node 118. For example, the monitoring agents 120 may include OS (Operating System) monitoring agent, log monitoring agent, script monitoring agent, SNMP (Simple Network Management Protocol agent) and the like. The monitoring agents 120 collect data from monitored computing nodes 118 and report the collected data to a monitoring server 112 or 116. In an embodiment, a monitoring agent 120 interacts with a single operating system or application and in most cases is located at the same computing node 118 where the operating system or application is running. A monitoring agent 120 may be an OS agent or a non-OS agent. OS agents may monitor the availability and performance of computing nodes 118 (e.g., Windows server), while non-OS agents may monitor the availability and performance of applications installed at the computing nodes 118. In an embodiment, a monitoring agent 120 is a software application implemented by at least one processor at the respective host computing node 118 hosting the monitoring agent 120.

A monitoring agent 120 monitors an operating system or application at a computing node 118 based on a monitoring configuration. A monitoring configuration is a set of definitions or conditions or events to test and may be used to raise alerts of the conditions and to trigger single action commands or automated workflows. A monitoring configuration may be configured to detect when specific conditions or events (e.g., slow transaction rates or invalid logon attempts) in an infrastructure occur, and in response, raise an alert. Each monitoring configuration may be assigned to one or more operating systems or applications that is to be monitored for specific events. An event monitored by a monitoring configuration may be pure or sampled. When the determination of an event is based on observations made at specific intervals, the event may be referred to as a sampled event. When an event is based on a spontaneous occurrence, the event may be referred to as a pure event. Thus, a definition for a sampled event generally includes an interval at which observations for the event are made. Definitions for pure events are not associated with intervals. An example of a sampled event is disk free space <10%. The sample event becomes true when the available disk space falls below 10% and later becomes false again after unwanted files are deleted and the disk space goes to 11% or higher. An example of a pure event is an event that monitors for an invalid user logon attempt. The event occurs when an invalid logon attempt is detected and is set to true. This event does not become a false once set to true. In order to monitor an operating system or application, a respective monitoring agent 120 may use a pre-defined monitoring configuration or a custom monitoring configuration specifically created for the operating system or application being monitored.

As shown in FIG. 1 , each monitoring infrastructure 110 includes a plurality of monitoring servers 112 and 116 which act as a collection and control points for performance and availability data and alerts received from monitoring agents 120. For example, in monitoring infrastructure 110 a, monitoring agents 120 a (monitoring computing nodes 118 a) report performance and availability data to monitoring server 116 a, monitoring agents 120 b (monitoring computing nodes 118 b) report data to monitoring server 112 a and monitoring agents 120 c (monitoring computing nodes 1118 c) report data to monitoring server 116 b. Similarly, in monitoring infrastructure 110 b, monitoring agents 120 d (monitoring computing nodes 118 d) and monitoring agents 120 e (monitoring computing nodes 118 e) report performance and availability data to monitoring server 112 b, and monitoring agents 120 f (monitoring computing nodes 118 f) report data to monitoring server 116 c.

Each monitoring server 112 or 116 is also responsible for tracking the online or offline status of monitoring agents 120 reporting data to the monitoring server 112 or 116. Because of the number of functions a monitoring server 112 or 116 performs, large-scale enterprise networks usually include multiple monitoring servers to distribute the load, as shown in FIG. 1 . In an embodiment, one of the monitoring servers in each monitoring infrastructure 110 is designated as the hub monitoring server, and the remaining monitoring servers are termed remote monitoring servers which report their data to the hub monitoring server. For example, in monitoring infrastructure 110 a, monitoring server 112 a is a hub monitoring server and monitoring servers 116 a and 116 b are remote monitoring servers. Similarly, in monitoring infrastructure 110 b, monitoring server 112 b is a hub monitoring server and monitoring server 116 c is a remote monitoring server.

Each monitoring server 112 or 116 is located on its own computer and has a unique monitoring server name. The architectures of various remote monitoring servers 116 may differ from each other and from the hub monitoring server 112. For example, a remote monitoring server 116 running on UNIX may report to a hub monitoring server running on Windows.

A user may access data from a monitoring server 112 or 116 using a portal client 122. As shown, monitoring infrastructure 110 a includes a portal client 122 a connected to the hub monitoring server 112 a. Similarly, monitoring infrastructure 110 b includes a portal client 122 b connected to the hub monitoring server 112 b. An optional portal server (not shown) may provide presentation and communication services for each portal client 122. The portal server may provide the core presentation layer for retrieval, manipulation, analysis, and pre-formatting of data. The portal server may retrieve data from the hub monitoring server 112 in response to user actions at the portal client 122 and send the data back to the portal client 122 for presentation. The portal server may also provide presentation information to the portal client 122 so that the portal client 122 can render the user interface views suitably. In an embodiment, the services of portal server may be integrated into the hub monitoring server 112, and the hub monitoring server 112 may be configured to provide presentation and communication services for each portal client 122.

While FIG. 1 shows the portal clients 122 connected to the hub monitoring servers 112, a skilled person may appreciate that one or more of the remote monitoring servers 116 may have their own respective portal clients which may be used to access data from the one or more remote monitoring servers 116.

In certain embodiments, the monitoring infrastructures 110 may not have the ability to install monitoring agents 120 at the respective host computing nodes 118. In such a case, a separate deployment server may be used to deploy the monitoring agents 120 at the host computing nodes. For example, as shown in FIG. 1 , the monitoring system 100 further includes a deployment server 130 configured to deploy monitoring agents 120 at respective host computing nodes 118. The deployment server 130 is further configured to collect log data recorded during deployment of a monitoring agent 120. The log data may include results of deploying one or more monitoring agents 120 at a host computing node 118. Deploying a monitoring agent 120 at a host computing node 118 includes installing the monitoring agent 120 at the host computing node 118. The deployment server 130 may belong to any third-party service provider which provides monitoring agent deployment services. The methods employed by the deployment server 130 to install the monitoring agents 120 and collect log data is beyond the scope of this disclosure and will not be described in further detail.

Central Monitoring Server and Central Client Device

As shown in FIG. 1 , the monitoring system 100 also includes a central monitoring server 102 which is configured to manage a plurality of monitoring infrastructures such as monitoring infrastructures 110 a and 110 b. A central client device 104 may provide a front-end user interface which may be used by a user to provide input parameters and trigger one or more jobs related to the monitoring infrastructures 110. A job in computing terminology generally refers to a process including a set of steps to accomplish a computing task such as deploying a monitoring agent 120 at a host computing node 118 or retrieving log data from a monitoring agent 120. Additionally, data retrieved from the monitoring infrastructures (e.g., log data) may be presented to the user using the front-end interface of the central client device 104. In an embodiment, the front-end interface may be a web application implemented using any conventional technology such as Java Server Pages (JSP). In an embodiment, the central monitoring server 102 may be any conventional webserver that can handle HTTP (Hypertext Transfer Protocol) request and response such as an Apache Tomcat Webserver. Further, the central monitoring server 102 may be a Linux or Windows based server.

In an embodiment, the front-end interface may be representative of a component of a client-server application (or other distributed application) which can communicate with the server 102 over the network 150. For example, the front-end interface may be a “thin” client where the processing is largely directed by the front-end application but performed by the server 102.

The central monitoring server 102 may include a monitoring manager 106 configured to manage the monitoring infrastructures 110. In certain embodiments, the monitoring manager 106 may be configured to manage deployment of monitoring agents 120 at the host computing nodes 118. For example, the monitoring manager 106 may trigger execution of a deployment job at the deployment server 130 based on user input parameters obtained from the front-end interface of the central client device 104 and may cause the deployment server 130 to deploy a specified monitoring agent 120 at one or more specified host computing nodes 118.

The user may initiate deployment of a monitoring agent 120 using the front-end interface of the central client device 104 by providing one or more input parameters to be used for the deployment. The input parameters may include one or more of an identity (ID) of the user, an indication of the monitoring agent 120 to be deployed, and identities of one or more host computing nodes 118 at which the indicated monitoring agent 120 is to be deployed. The monitoring manager 106 may be configured to perform a number of tasks related to monitoring agents 120 including deployment of monitoring agents, restarting monitoring agents 120 and collecting log data from monitoring agents 120. In this context, the user input parameters provided by the user at the front-end interface of the central client device 104 may additionally include a type of task to be performed (e.g., deploy monitoring agent, restart monitoring agent, collect log data from a monitoring agent etc.) in relation to the indicated monitoring agent 120.

The user may either type the input parameters in respective text fields provided at the front-end interface or may select each value of the input parameter from a respective list of values for the parameter. For example, the user may select the type of task to be performed from a list of available tasks that may be performed in relation to a monitoring agent. The list of tasks may include deploying a monitoring agent, restarting a monitoring agent and collecting log data from a monitoring agent. Similarly, the user may select the identity of the monitoring agent 120 from a list of available monitoring agents 120 and may select the identities of the host computing nodes 118 from a list of host computing nodes 118. For example, the list of monitoring to agents 120 may include OS (Operating System) monitoring agent, log monitoring agent, script monitoring agent, SNMP (Simple Network Management Protocol agent) and the like. The list of host computing nodes 118 may include a list of all host computing nodes (or a subset thereof) in the monitoring infrastructures 110 a and 110 b.

In an embodiment, the front-end application at the central client device 104 or the monitoring manager 106 may check for errors in the user provided input. For example, the user inputs may be checked for typographical errors, format errors (e.g. format of the host computing node identities or monitoring agent identities) and the like, and the user may be notified of any identified errors in the user inputs or the errors may be corrected automatically.

After providing information relating to identity (ID) of the user, an indication of the monitoring agent 120 to be deployed and identities of one or more host computing nodes 118 at which the indicated monitoring agent 120 is to be deployed, the user may trigger the deployment of the identified monitoring agent 120 from the central client device 104, for example, by selecting a button on a user interface screen of the front-end application.

Once the deployment of the monitoring agent 120 is triggered at the central client device 104, the monitoring manager 106 generates a unique trace log file to record information relating to the deployment. For example, the monitoring manager 106 may record the user ID of the user triggering the deployment, a unique job ID of a job executed for carrying out the deployment, a time of triggering the deployment by the user, and the user input parameters specified for the deployment. The monitoring manager 106 records in the trace log file every transaction during the deployment starting from obtaining user input at the central client device 104 to completing deployment of the monitoring agent 120 at the respective one or more host computing nodes 118.

The monitoring manager 106 may be configured to validate an access level of the user that triggered a task (e.g., deployment of monitoring agent 120) and checks whether the user is authorized to perform the task based on the user's level of access. Three different levels of access may be defined to provide proper authorization to users. Users with an engineering level access may execute jobs at development computing nodes only. Users with operations level access may execute jobs at development as well as production computing nodes. Users with no access may not execute any jobs. The monitoring manager 106 allows a job to be executed only if the user triggering the job has the appropriate level of access to execute the job on the specified one or more host computing nodes 118. In an embodiment, a user access matrix is stored at the central monitoring server 102 which includes a list of registered user IDs and a respective level of access associated with each user ID. The monitoring manager 106 searches the user access matrix based on the user ID specified by the user and determines the user's level of access from the access matrix.

The monitoring manger 106 may be configured to identify a type of each host computing node 118 based on the identity of the host computing node provided by the user as part of user input. For example, a host computing node 118 may be a production node or a non-production node such as a development node or a test node. The central monitoring server 102 stores an inventory of host computing nodes 118 in the monitoring infrastructures 110 a and 110 b, and further stores information relating to the type of each computing node 118 (e.g., whether each host computing node 118 is a production server or a non-production server). The monitoring manager 106 may query the inventory based on the identities of the host computing node 118 specified by the user as part of user input to determine the type of each specified host computing node 118.

The monitoring manager 106 may be configured to determine whether the user is authorized to perform the requested task (e.g., deployment of a monitoring agent 120) based on the user's level of access (e.g., determined based on the user matrix) and the type of the specified one or more host computing nodes (e.g., determined based on the inventory of host computing nodes). For example, if a specified host computing node 118 is determined to be a production node (e.g., based on the inventory) and the user's level of access (e.g., based on the user matrix) includes deployment access on production nodes, the monitoring manager 106 determines that the user has authorization for performing the deployment of the specified monitoring agent 120 at the specified host computing node 118.

The monitoring manager 106 may be configured to identify based on the user input an appropriate job which can be executed to carry out a requested task (e.g., deployment of a specified monitoring agent 120, collection of log etc.) at a specified host computing node 118. As described above, a job in computing terminology generally refers to a process including a set of steps to accomplish a computing task such as deploying a monitoring agent 120 at a host computing node 118 or retrieving log data from a monitoring agent 120. The identified job may be custom for the specified task (e.g., deployment, collection of log data etc.), the specified host computing node (e.g., custom for production or non-production node) and for the specified type of monitoring agent 120. The monitoring manager 106 may identify an appropriate job to be executed based on one or more of the specified type of task to be performed (e.g., deploy, collect log data etc.), the specified monitoring agent 120 and the specified host computing node 118. For example, when a user triggers a deployment of a Linux monitoring agent at a host computing node 118 that is a production node, the monitoring manager 106 selects a job designed to deploy a Linux monitoring agent at production nodes. The central monitoring server 102 may store a list of jobs, wherein each job is custom designed for a set of parameters including one or more of the type of requested task, the type of monitoring agent 120, the service role to be used for the task (described below) and the host computing node 120 at which the task is to be performed. Each job is identified by a unique job ID. The monitoring manager 106 may select a job from the list of jobs based on the user input parameters. In an embodiment, each job is associated with one or more software programs (e.g., a shell script), wherein the software program includes software code to perform the set of steps to perform the task for which the job is designed. A job may be executed by executing the one or more software programs.

The monitoring manager 106 is configured to determine a job path for accessing the job selected for carrying out the requested task. For example, the job path may point to a location in the monitoring system 100 where the job and associated one or more software programs are stored. A job and associated one or more software programs may be stored at the central monitoring server 102, the deployment server 130, monitoring servers 112 or 116 or anywhere in the monitoring system 100.

The monitoring manager 106 may be configured to determine an execution time window associated with each specified host computing node 118. The execution time window associated with a host computing node 118 may be a time interval within which jobs are allowed to be executed at the host computing node 118. For example, the execution time window may be set for a host computing node 118 during periods of relative inactivity (e.g., time periods with lower usage of processing resources) such as non-business hours. The central monitoring server 102 may store the execution time windows configured for each host computing node in the inventory of host computing nodes 118. The monitoring manager 106 may query the inventory based on the identities of the host computing node 118 specified by the user to determine the respective execution time windows. Additionally or alternatively, the monitoring manager may query a specified host computing node 118 and receive information related to the execution time window directly from the host computing node 118. Once the execution time window of a specified host computing node 118 is identified, the monitoring manager 106 then configured to determine a time of execution within the execution time window of the host computing node 118. The time of execution may relate to the time at which the monitoring manager 106 is to trigger execution of the identified job at the deployment server 130. The monitoring manager 106 may set the time of execution at any time within the execution time window, for example, at the start of the execution time window or anytime during the execution time window.

In an embodiment, the monitoring manager 106 determines a geographic location (e.g., region, country, state, city, province, etc.) of a specified host computing node 120 and determines the local time zone at the determined geographic location. The inventory of the host computing nodes 118 maintained at the central monitoring server 102 may further include geographical locations of the host computing nodes 118. The monitoring manager may query the inventory based on identities of the host computing nodes 118 specified by the user to determine the respective geographical regions of the nodes. Once the time zone associated with a specified host computing node 118 is identified, the monitoring manager 106 may convert the execution time window of the host computing node 118 to the time zone of the central monitoring server 102. In an embodiment, the monitoring manager determines the time of execution in accordance with the time zone of the central monitoring server 102.

The monitoring manager 106 may be configured to determine an estimated time for completion of a requested task such as deployment of a specified monitoring agent 120 at a specified host computing node 118. The monitoring manager 106 may determine the estimated time for completion of the deployment based on historical data related to deploying the same or similar monitoring agent 120 at one or more host computing nodes 118 having similar configuration and/or capabilities as the specified host computing node 118. For example, the historical data may include time taken to deploy the same or similar monitoring agent 120 at one or more similar host computing nodes 118, time taken to communicate a copy of the monitoring agent 120 to the specified host computing node 118 and a processing latency associated with the specified host computing node 118.

The monitoring manager 106 may be configured to compare the estimated time for completion of the requested task (deployment of a specified monitoring agent 120) at the specified host computing node 118 with the length of the execution time window associated with the host computing node 118 and determine whether the length of the execution time window is sufficiently long to complete the task. If the length of the execution time window is not sufficiently long to complete the task, the monitoring manager 106 generates an error for display to the user at the central client device 104.

The monitoring manager 106 is configured to identify a service role to be used to execute an identified job based on the type of task to be completed. For example, the service role may include a deployment service role for deployment of a monitoring agent 120 or a discovery service role for collecting log data from a monitoring agent 120. A service role may define an extent of authorization, for example, to access deployment directories and limits access to only those systems and data required to complete the specified task. The monitoring manager 106 is configured to select a service account for the specified task based on the identified service role. A service account does not require human intervention may be used to access the deployment server 130 and to establish connection with the deployment server 130.

The monitoring manager 106 is configured to generate an input file (e.g., an input text file) including information relating to one or more user input parameters and one or more additional input parameters generated based on the user input parameters. The input file may include information relating to one or more of the identity of the job selected for performing a specified task (e.g., deploying agent, collecting log data etc.), the job path for accessing the job, identities of one or more host computing nodes 118 where the specified task is to be executed, the identity of the monitoring agent 120, the execution time window associated with each specified host computing node 118, the time of execution, the geographic location of each specified host computing node 120, the estimated time for completion of the specified task, the service role to be used for the executing the job and other additional input parameters specified by the user. In one example, the generated input file includes information relating to the identity of the job selected for performing a specified task (e.g., deploying monitoring agent, collecting log data etc.), the job path for accessing the job, identities of one or more host computing nodes 118 where the specified task is to be executed, the estimated time for completion of the specified task and the service role to be used for executing the job at the deployment server 130.

Once all error checks and validations are completed and required input parameters for completing the requested task are obtained or determined, the monitoring manager 106 is configured to access the deployment server 130 using the selecting service account that does not require human intervention and has the appropriate level of access to execute the selected job. Accessing the deployment server 130 may include automatically logging into the deployment server 130 using the service account. Upon successfully accessing the deployment server 130, the monitoring manager 106 establishes a connection with the deployment server 130 and triggers execution of the selected job based on the user input parameters to cause the deployment server 130 to perform the task requested by the user. For example, once a connection is established between the central monitoring server 102 and the deployment server 130, the monitoring manager 106 transfers a copy of the generated input file to the deployment server 130 and triggers execution of the selected job at the deployment server 130 based on the input parameters specified in the input file. For example, when the user specified task is to deploy a specified monitoring agent 120 at a specified host computing node 118, the monitoring manager 106 triggers execution of a selected deployment job at the deployment server 130 at the determined time of execution. Triggering execution of the deployment job causes the deployment server to extract input parameters from the input file (e.g., including the identity of the job, job path, target host computing node 118, service role etc.) and carry out the deployment task based on the extracted input parameters. For example, triggering the execution of the job causes the deployment server 130 to access the job using the specified job path and execute the job to install the specified monitoring agent 120 at the specified host computing node 118 using the specified service role.

After triggering the execution of the selected job at the deployment server 130, the monitoring manager 106 may be configured to wait for a time period that equals or exceeds the estimated time for completion of the requested task and re-access the deployment server 130 using the service account and re-establish a connection between the central monitoring server 102 and the deployment server 130. Once the connection with the deployment server 130 is re-established, the monitoring manager retrieves results of the execution and presents the results to the user using the front-end interface at the central client device 104. In an embodiment, the deployment server 130 generates a unique identification each time a job is executed at the deployment server 130, wherein each identification uniquely identifies a corresponding execution of a job. The monitoring manager 106 obtains the unique identification of the execution of the selected job from the deployment server 130 and requests the results of the execution after re-establishing the connection based on the obtained identification.

The monitoring manager 106 may be configured to examine the results of the execution obtained from the deployment server 130 and re-trigger the execution of the job at the next execution window if the execution was unsuccessful. The method for re-triggering the execution of the job is similar to the initial triggering of the execution of the job described above.

As shown in FIG. 1 all components of the monitoring system 100 may be connected to a network 150 and may communicate with each other over the network 150. The network 150, in general, may be a wide area network (WAN), personal area network (PAN), a cellular network, or any other technology that allows devices to communicate electronically with other devices. In one or more embodiments, the network 150 may be the internet.

Each of the computing nodes 118 may include a computing device running one or more software applications. For example, a computing node 118 may be representative of a computing system hosting software applications that may be installed and run locally or may be used to access software applications running on a server. The computing system may include mobile computing systems including smart phones, tablet computers, laptop computers, or any other mobile computing devices or systems capable of running software applications and communicating with other devices. The computing system may also include non-mobile computing devices such as desktop computers or other non-mobile computing devices capable of running software applications and communicating with other devices.

FIG. 2 illustrates a flowchart of an example method 200 for deploying a monitoring agent (e.g., monitoring agent 120) at a host computing node (e.g., host computing node 118), in accordance with certain embodiments of the present disclosure. In an embodiment the method 200 may be performed by the monitoring manager 106 of the central monitoring server 102 shown in FIG. 1 .

At step 202, the monitoring manager 106 obtains user input parameters from the front-end user interface at the central client device 104. The user may initiate deployment of a monitoring agent 120 using the front-end interface of the central client device 104 by providing one or more input parameters to be used for the deployment. The input parameters may include one or more of an identity (ID) of the user, an indication of the monitoring agent 120 to be deployed, and identities of one or more host computing nodes 118 at which the indicated monitoring agent 120 is to be deployed. The user may either type the input parameters in respective text fields provided at the front-end interface or may select each value of the input parameter from a respective list of values for the parameter. For example, the user may select the type of task to be performed from a list of available tasks that may be performed in relation to a monitoring agent. The list of tasks may include deploying a monitoring agent, restarting a monitoring agent and collecting log data from a monitoring agent. Similarly, the user may select the identity of the monitoring agent 120 from a list of available monitoring agents 120 and may select the identities of the host computing nodes 118 from a list of host computing nodes 118. For example, the list of monitoring agents 120 may include OS (Operating System) monitoring agent, log monitoring agent, script monitoring agent, SNMP (Simple Network Management Protocol agent) and the like. The list of host computing nodes 118 may include a list of all host computing nodes (or a subset thereof) in the monitoring infrastructures 110 a and 110 b.

After providing information relating to identity (ID) of the user, an indication of the monitoring agent 120 to be deployed and identities of one or more host computing nodes 118 at which the indicated monitoring agent 120 is to be deployed, the user may trigger the deployment of the identified monitoring agent 120 from the central client device 104, for example, by selecting a button on a user interface screen of the front-end application.

In an embodiment, the front-end interface may be a web application implemented using any conventional technology such as Java Server Pages (JSP). In an embodiment, the central monitoring server 102 may be any conventional webserver that can handle HTTP (Hypertext Transfer Protocol) request and response such as an Apache Tomcat Webserver. Further, the central monitoring server 102 may be a Linux or Windows based server.

At step 204, the monitoring manager performs a number of checks and validations based on the obtained user input parameters. For example, once the deployment of the monitoring agent 120 is triggered by the user at the central client device 104, the monitoring manager 106 validates an access level of the user and checks whether the user is authorized to perform the task based on the user's level of access. Three different levels of access may be defined to provide proper authorization to users. Users with an engineering level access may execute jobs at development computing nodes only. Users with operations level access may execute jobs at development as well as production computing nodes. Users with no access may not execute any jobs. The monitoring manager 106 allows a job to be executed only if the user triggering the job has the appropriate level of access to execute the job on the specified one or more host computing nodes 118. In an embodiment, a user access matrix is stored at the central monitoring server 102 which includes a list of registered user IDs and a respective level of access associated with each user ID. The monitoring manager 106 searches the user access matrix based on the user ID specified by the user and determines the user's level of access from the access matrix.

The monitoring manger 106 further identifies a type of each host computing node 118 specified by the user based on the identity of the host computing node provided by the user as part of user input. For example, a host computing node 118 may be a production node or a non-production node such as a development node or a test node. The central monitoring server 102 stores an inventory of host computing nodes 118 in the monitoring infrastructures 110 a and 110 b, and further stores information relating to the type of each computing node 118 (e.g., whether each host computing node 118 is a production server or a non-production server). The monitoring manager 106 queries the inventory based on the identities of the host computing node 118 specified by the user as part of user input to determine the type of each specified host computing node 118.

The monitoring manager 106 determines whether the user is authorized to perform the requested deployment of a monitoring agent 120 based on the user's level of access (e.g., determined based on the user matrix) and the type of the specified one or more host computing nodes 118 (e.g., determined based on the inventory of host computing nodes). For example, if a specified host computing node 118 is determined to be a production node (e.g., based on the inventory) and the user's level of access (e.g., based on the user matrix) includes deployment access on production nodes, the monitoring manager 106 determines that the user has authorization for performing the deployment of the specified monitoring agent 120 at the specified host computing node 118.

In an embodiment, the front-end application at the central client device 104 or the monitoring manager 106 may check for errors in the user provided input. For example, the user inputs may be checked for typographical errors, format errors (e.g. format of the host computing node identities or monitoring agent identities) and the like, and the user may be notified of any identified errors in the user inputs or the errors may be corrected automatically.

In an example, once the deployment of the monitoring agent 120 is triggered at the central client device 104, the JSP front-end passes the user input parameters to a Java servlet at the central monitoring server 102. The Java servlet may be managed and run by the monitoring manager 106 at the central monitoring server 102. The servlet performs the various checks and validations described above based on the user input parameters obtained from the JSP front-end.

At step 206, the monitoring manager 106 checks whether the checks and validations described above were successful. If one or more of the above checks and validations are determined to be unsuccessful, the monitoring manager 106 terminates the deployment and the method 200 ends here. On the other hand, if all checks and validations are successful the method 200 proceeds to step 208 where the monitoring manager 106 determines a number of parameters to be used for the requested deployment.

The monitoring manager 106 identifies based on the user input an appropriate job which can be executed to carry out the deployment of the specified monitoring agent 120 at a specified host computing node 118. As described above, a job in computing terminology generally refers to a process including a set of steps to accomplish a computing task such as deploying a monitoring agent 120 at a host computing node 118 or retrieving log data from a monitoring agent 120. The identified job may be custom for deployment of the monitoring agents, the specified host computing node (e.g., custom for production or non-production node) and for the specified type of monitoring agent 120. The monitoring manager 106 may identify an appropriate job to be executed for deployment of the specified monitoring agent 120 at the specified host computing node 118. For example, when a user triggers a deployment of a Linux monitoring agent at a host computing node 118 that is a production node, the monitoring manager 106 selects a job designed to deploy a Linux monitoring agent at production nodes. The central monitoring server 102 may store a list of jobs, wherein each job is custom designed for a set of parameters including one or more of the type of requested task (e.g., deployment of the monitoring agent 120), the type of monitoring agent 120, the service role to be used for the task (described below) and the host computing node 120 at which the task is to be performed. Each job is identified by a unique job ID. The monitoring manager 106 may select a job from the list of jobs based on the user input parameters. In an embodiment, each job is associated with one or more software programs (e.g., a shell script), wherein the software program includes software code to perform the set of steps to perform the task for which the job is designed. A job may be executed by executing the one or more software programs.

The monitoring manager 106 determines a job path for accessing the job selected for carrying out the deployment of the specified monitoring agent 120 at the specified host computing node 118. For example, the job path may point to a location in the monitoring system 100 where the job and associated one or more software programs are stored. A job and associated one or more software programs may be stored at the central monitoring server 102, the deployment server 130, monitoring servers 112 or 116 or anywhere in the monitoring system 100.

The monitoring manager 106 determines an execution time window associated with the specified host computing node 118. The execution time window associated with a host computing node 118 may be a time interval within which jobs are allowed to be executed at the host computing node 118. For example, the execution time window may be set for a host computing node 118 during periods of relative inactivity (e.g., time periods with lower usage of processing resources) such as non-business hours. The central monitoring server 102 may store the execution time windows configured for each host computing node in the inventory of host computing nodes 118. The monitoring manager 106 may query the inventory based on the identities of the host computing node 118 specified by the user to determine the respective execution time windows. Additionally or alternatively, the monitoring manager may query the specified host computing node 118 and receive information related to the execution time window directly from the host computing node 118.

Once the execution time window of the specified host computing node 118 is identified, the monitoring manager 106 then determines a time of execution within the execution time window of the host computing node 118. The time of execution may relate to the time at which the monitoring manager 106 is to trigger execution of the identified job at the deployment server 130. The monitoring manager 106 may set the time of execution at any time within the execution time window, for example, at the start of the execution time window or anytime during the execution time window.

In an embodiment, the monitoring manager 106 determines a geographic location (e.g., region, country, state, city, province, etc.) of the specified host computing node 120 and determines the local time zone at the determined geographic location. The inventory of the host computing nodes 118 maintained at the central monitoring server 102 may further include geographical locations of the host computing nodes 118. The monitoring manager may query the inventory based on the identity of the host computing node 118 specified by the user to determine the respective geographical region of the node. Once the time zone associated with the specified host computing node 118 is identified, the monitoring manager 106 may convert the execution time window of the host computing node 118 to the time zone of the central monitoring server 102. In an embodiment, the monitoring manager determines the time of execution in accordance with the time zone of the central monitoring server 102.

The monitoring manager 106 determines an estimated time for completion of the requested deployment of a specified monitoring agent 120 at a specified host computing node 118. The monitoring manager 106 may determine the estimated time for completion of the deployment based on historical data related to deploying the same or similar monitoring agent 120 at one or more host computing nodes 118 having similar configuration and/or capabilities as the specified host computing node 118. For example, the historical data may include time taken to deploy the same or similar monitoring agent 120 at one or more similar host computing nodes 118, time taken to communicate a copy of the monitoring agent 120 to the specified host computing node 118 and a processing latency associated with the specified host computing node 118.

The monitoring manager 106 may be configured to compare the estimated time for completion of the deployment of the specified monitoring agent 120 at the specified host computing node 118 with the length of the execution time window associated with the host computing node 118 and determine whether the length of the execution time window is sufficiently long to complete the deployment. If the length of the execution time window is not sufficiently long to complete the deployment, the monitoring manager 106 generates an error for display to the user at the central client device 104. In an embodiment the monitoring manager triggers the execution of the deployment job only when the length of the execution time window is sufficiently long to complete the requested deployment.

The monitoring manager 106 identifies a service role to be used to execute the identified job for the deployment. For example, the service role may include a deployment service role for deployment of the monitoring agent 120. A service role may define an extent of authorization, for example, to access deployment directories and limits access to only those systems and data required to complete the specified task. The monitoring manager 106 selects a service account for the specified task based on the identified service role. A service account does not require human intervention may be used to access the deployment server 130 and to establish connection with the deployment server 130.

At step 210, the monitoring manager generates an input file (e.g., an input text file) including information relating to one or more user input parameters and one or more additional input parameters generated based on the user input parameters. The input file may include information relating to one or more of the identity of the job selected for performing the requested deployment, the job path for accessing the job, identity of the host computing node 118 where the deployment is to be executed, the identity of the monitoring agent 120 that is to be deployed at the host computing node 118, the execution time window associated with the specified host computing node 118, the time of execution, the geographic location of each specified host computing node 120, the estimated time for completion of the deployment, the service role to be used for the executing the selected deployment job and other additional input parameters specified by the user. In one example, the generated input file includes information relating to the identity of the job selected for performing the deployment, the job path for accessing the job, identity of the host computing node 118, the estimated time for completion of the deployment and the service role to be used for executing the job at the deployment server 130.

At step 212, the monitoring manager 106 accesses the deployment server 130 and establishes a connection between the central monitoring server 102 and the deployment server 130. As described above, once all error checks and validations are completed and required input parameters for completing the requested task are obtained or determined, the monitoring manager 106 accesses the deployment server 130 using the selecting service account that does not require human intervention and has the appropriate level of access to execute the selected job. Accessing the deployment server 130 may include automatically logging into the deployment server 130 using the service account. Upon successfully accessing the deployment server 130, the monitoring manager 106 establishes a connection with the deployment server 130.

At step 214, the monitoring manager 106 triggers execution of the deployment job at the deployment server based on the input parameters. Upon successfully accessing the deployment server 130 and establishing a connection with the deployment server 130, the monitoring manager 106 triggers execution of the selected deployment job based on the user input parameters to cause the deployment server 130 to perform the deployment requested by the user. For example, once a connection is established between the central monitoring server 102 and the deployment server 130, the monitoring manager 106 transfers a copy of the generated input file to the deployment server 130 and triggers execution of the selected job at the deployment server 130 based on the input parameters specified in the input file. For example, the monitoring manager 106 triggers execution of the selected deployment job at the deployment server 130 at the determined time of execution. Triggering execution of the deployment job causes the deployment server to extract input parameters from the input file (e.g., including the identity of the job, job path, target host computing node 118, service role etc.) and carry out the deployment task based on the extracted input parameters. For example, triggering the execution of the job causes the deployment server 130 to access the job using the specified job path and execute the job to install the specified monitoring agent 120 at the specified host computing node 118 using the specified service role.

At step 216, the monitoring manager checks whether a pre-determined wait time has elapsed after triggering the execution of the deployment job at the deployment server 130. The wait time equals or exceeds the estimated time for completion of the deployment previously determined by the monitoring manager 106. As described above, after triggering the execution of the selected deployment job at the deployment server 130, the monitoring manager 106 waits for a time period that equals or exceeds the estimated time for completion of the deployment task.

Once the wait time has elapsed, the method 200 proceeds to step 218 where the monitoring manager 106 re-accesses the deployment server 130 using the service account and re-establishes a connection between the central monitoring server 102 and the deployment server 130. Once the connection with the deployment server 130 is re-established, the monitoring manager retrieves results of the execution. In an embodiment, the deployment server 130 generates a unique identification each time a job is executed at the deployment server 130, wherein each identification uniquely identifies a corresponding execution of a job. The monitoring manager 106 obtains the unique identification of the execution of the selected job from the deployment server 130 and requests the results of the execution after re-establishing the connection based on the obtained identification.

At step 220, the monitoring manager 106 checks whether the execution of the deployment job was successful based on the obtained results of executing the deployment job by the deployment server 130. If the monitoring manager determines based on the results that the deployment was successful, the method ends here.

However, if the monitoring manager 106 examines the results of the execution obtained and determines that the deployment was unsuccessful, the method proceeds to step 222 where the monitoring manager re-triggers the execution of the job at the next execution window.

In an example, once the Java servlet performs the various checks and validations at step 204, the servlet calls a script program, also managed by the monitoring manager 106, that executes a set of commands to perform steps 206-220 of the method 200. In an embodiment, data related to results of the execution of the deployment job and other error messages may be passed back to the servlet and then to the JSP front-end for presentation to the user on the central client device 104.
